Bosch Automotive USA has the worst possible customer service. I installed one of there water pumps in my Chevy work van and within two days the pump valve fell off and left me stranded out of state.
After 5 phone calls and 2 emails they will not respond! They have an employee tell me they will email the warranty department on my behalf and then they transfer my call and all you can do is leave a detailed message. They never call back! Faulty part, no quality control, and no customer service.
I went from thinking they were a higher end company to understanding they make junk that they will not stand behind.
